Hardware support comparison

AIX is built to run on IBM Power Systems, and to fully exploit the new technologies introduced with each generation. Below you’ll find the recommended levels for each version and technology level, but also consider what hardware compatibility mode you’ll be able to run in with each version. You’ll always get the best performance and efficiency on the latest generation’s native mode.

AIX release roadmap

Technology Levels (TLs) are minor releases that allow you to take advantage of new features without major disruption. TLs have a lifecycle of 3 to 4 years, depending on the frequency and maturity of the release. Past the end of the last TL’s lifecycle, IBM offers both Service Extension and sometimes Extended Support options for each AIX Version.

AIX Editions

You can purchase AIX either on its own, or bundled with supporting software. Both editions can be ordered with either of the currently offered versions: AIX 7.1 or AIX 7.2.

 

AIX Standard Edition

(Product ID: 5765-G98)

This is the AIX operating system –it’s the platform you want for your mission critical data. And it fully takes advantage of the IBM Power Systems platform.


AIX Enterprise Edition V1.2

(Product ID: 5765-CD1 for AIX 7.1, 5765-CD3 for AIX 7.2)

In addition to the AIX Standard Edition operating system, this includes software to help effectively manage, optimize and secure your Power Systems infrastructure.


Running AIX Version 5.X applications

Migrate to AIX V7 and POWER8

Be assured of your software compatibility with the binary compatibility guarantee.

POWER8 support for AIX 5.3

Run these workloads natively on POWER8 for a limited time.

Run AIX 5.X applications under AIX V7 with versioned workload partitions

Minimize the effort to consolidate older AIX workloads on the latest generation of Power Systems servers. Now you can more efficiently manage the lifecycle of your legacy AIX environments.
